HAND-PROPELLED MOTOR-BOAT.

Specification of Letters Patent.

Application filed. May 28, 1909. Serial No. 498,794.

b all whom it may concern:

Be it known that I, MAGELLAN ALBER- MAN, a citizen of the United States,residing at Osprey, in the county of Manatee and State of Florida, haveinvented certain new and useful Improvements in Hand-PropelledMotor-Boats, of which the following is a specification.

This invention relates to certain new and useful improvements inmanually-operated motor boats.

The object of my invention is to provide a simply constructed, effectiveand readily operated motor, arranged for use in light pleasure boats,enabling the operator to obtain a greater speed than is possible withthe use of cars at the expenditure of the same amount of manual power.

lVith these and other objects in view the invention consists in thecombination and arrangement of parts, as will be hereinafter more fullydescribed, and particularly pointed out in the claims, it beingunderstood that changes in the specific structure shown and describedmay be made within the scope of the claims without departing from thespirit of the invention.

In the drawings forming a portion of this specification, and in whichlike characters of reference indicate similar parts in the severalviews, Figure 1 is a fragmentary sectional view taken through the sternportion of a boat provided with my propelling mechanism, Fig. 2 is a topplan view thereof, Fig. 8 is a detail front view of the rock lever, Fig.1 is a front view of the internal gear and connecting shaft.

In the accompanying drawings, 5 represents the stern end of a pleasureboat pro- ,vided with the usual stern seat 6 and rudder 7. The seat 6 issupported by means of a post 8. Secured to this post 8 is a bearing 9,this bearing supporting a stub shaft 10 which stub shaft in turn carriesthe beveled gear 11 provided with a wrist pin 12 from which extends thecrank rod 13 as clearly indicated in Fig. 1.

Held to a bearing within the post 8 is the driving shaft 14 which at itsrear end is held within the bearing 15 secured to the stern of the boat.This shaft 14 is provided with an internal gear 15 which is made heavyenough to serve the purposes of a fly wheel. The outer peripheral edgeof this internal gear is rounded as is shown at 16 so as to present aconvenient edge to be grasped by the hand of the operator. EX- ten-dingfrom and forming a portion of this internal gear 15 is the exteriorlyconnected bevel gear 17 which also serves as the hub of the fly wheelforming gear 15. This gear 1'7 is in mesh with the bevel gear 11 uponthe shaft 10 which is disclosed in Fig. 1.

Held within the bearings 19 and 20 and secured to the stern of the boat,as disclosed in Fig. 1 is the propeller shaft 21 at one end carrying thepropeller 22 and at the other end is the pinion 23 meshing with theinternal gear 15 as disclosed.

At a suitable point. in front of the seat 6 I provide the supportingbracket 25 which near its upper end has the supporting pin 26 carryingthe rock lever 27 as disclosed in Fig. 3. This lever at its upper endhas the operating handle 28 while the lower end is forked to provide theslot 29 within which the front end of the crank rod 13 is held, the rodbeing secured by means of the pin 30. The lower forked ends of thisoperating rock lever are slotted as disclosed at 31 to slidably receivethe threaded end 32 of the foot rest 33 as clearly indicated in Fig. 8.By means of suitable nuts 84:, these foot rests are secured to the rocklever. The seat 6 as disclosed in Fig. 2 is recessed or slotted as shownat a; to provide access openings so that the operator can reach down andgrasp the outer peripheral edge of the fly wheel 15 in starting themachine, stopping it or reversing the propeller.

The operator in driving the motor grasps the handle 28 while at the sametime placing his feet upon the foot rest 33. Then in imparting a rockingmotion to the lever 27, the propeller 22 will be revolved by means ofthe intermediate gearing as disclosed. The rock lever 27 is providedwith a plurality of openings 38 within which the pin is adjustably heldso as to regulate the stroke of the lever 27. By this arrangement a highspeed may be imparted to the propeller 22.

The rounded smooth edge 16 of the fly wheel provides a ready hand-holdfor the operator who can thereby not only check the speed of the wheelin stopping the propeller but can also instantly reverse the propeller.

And having thus described my said invention, what I claim as new anddesire to se cure by United States Letters Patent is:

1. The combination with a boat having a stern seat provided with twoaccess openings, of a drive shaft beneath said seat, an internal gearserving as a fly wheel and having an exterior connected bevel gear, apropeller shaft extending through the stern of the boat and providedwith a pinion mesh ing with said internal gear, a bevel gear mountedadjacent to said first mentioned bevel gear having a wrist pin, a crankrod extending from said pin, a rock lever pivoted intern'iediate of itsend, said crank rod being adjustably secured to said lever, anadjustably-secured foot rest secured to the lower end of said lever.

Q. The combination with a boat having a stern seat provided with twoaccess openings, of a drive shaftpositioned below said seat, an internalgear serving as a fly wheel and having an eXteriorly connected bevelgear secured to said drive shaft, a propeller shaft mounted below saiddrive shaft, a pinion carried upon said propeller shaft, and meshingwith said internal gear, a bevel gear mounted adjacent to said firstmentioned bevel gear having a Wrist pin, a crank rod extending from saidwrist pin, a rock lever having its end forked, a supporting pin securedto the forked end of said lever, a supporting bracket carrying said pin,said bracket being held between the forked ends of said lever, saidcrank rod being adjustably secured to said lever, and foot restsadjustably secured to the forked end of said operating lever.

In testimony whereof I atlix my signature, in presence of two witnesses.
